If you’re dressing up as Finn, Jake, Marceline, the Ice King, Lumpy Space Princess, Gunter, Shelby, Princess Bubblegum, or anyone else from the show this weekend, please shoot yourself (in a photograph kind of way) and upload the pictures straight to the Adventure Time Tumblr page. And Happy Halloween, everybody.

From “Blood under the Skin.” The episode’s lead designer was Phil Rynda. Natasha Allegri and Andy Ristaino were designers. The character clean-up artist was Alex Campos. Ron Russell and Simon Simmonds were the colorists. Pat McHale was the creative director. Nick Jennings is the show’s art director.

Five new Adventure Time T-shirts are now available over at the Mighty Fine website. Pretty, slick ones, too. BUT WAIT. The Mighty Fine folks want us to give away a shirt to one of you, our faithful readers. While we have only one to give away (boo), the winner gets his choice of any one of the five pictured here (hooray). Now, we need to note these are juniors (ladies’) sizes, S-XL, so big, brawny fellas like myself might be a bit disappointed. So here’s the deal: the first person to answer correctly the question at the bottom of the post gets the shirt. Post your answers in the comments. Go!

Too easy! The contest is over. Hats off to kieranpertnav who knew the last figure needed to perfect Princess Bubblegum’s decorpsinator serum was FOUR!

If you watched the episode last night, you may want to compare what you saw with this board by Somvilay and Kent. There are lots of differences, some subtle, some not so. Look for Princess Princess Princess’s pimple problem, the scene with Single Mom Pinata Princess, and Finn punching out Lumpy Space Princess’s lumps.

“Blood under the Skin” premieres next Monday night, November 1, at 8:00 p.m. As always, that’s Jeremy Shada and John Di Maggio as Finn & Jake. Jeff Bennett is the voice of Knight #1 and Peter Stormare is Sir Slicer.

From “Loyalty to the King.” “Loyalty’s” lead designer was Phil Rynda. Natasha Allegri, Andy Ristaino, and Bob Flynn were designers. The character clean-up artist was Alex Campos. Ron Russell and Simon Simmonds were the colorists. Pat McHale was the creative director. Nick Jennings is the show’s art director.
